Application led October 31, 1918.

To mit whom t may conce/rn:

ISe it known that I, Ammer I). Lun, a citizen of the United States, residing at Chicago, in the county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Duniping-Iioppers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

lVly invention relates to dumping hopper-s and more particularly to that class of hoppers which are adapted to roll on a runway from a central charge carrying to a limiting dumping position upon either side of the central position. My invention concerns itself more particularly with the means which hold the hopper in its central charge carrying position. The means which I employ are exceedingly simple and are very effective to hold the hopper not only against rolling from side to side but also to hold the hopper upon the runway when the vehicle `upon which it is placed rides over obstructions. In the preferred form of the invention holding means are duplicated at the two ends of the hopper and are so ari ranged that they move conjointly. I will describe one form which my invention may take more in detail by referring to the accompanying' drawings illustrating such embodiment in which- Figure l is a side view of a hopper provided with my improved holding mechanism;

Fig. 9. is an end view thereof, the hopper being shown in one of its limiting positions in dotted lines;

F ig. 3 is a sectional view on line 3,A 3 of Fig. 2; and

Fig. fl is a sectional View on line 1l, l of Fig. 2 certain parts being broken away more clearly to reveal features of` construction.

In the drawings I show a hopper l0 operating upon runways ll. This hopper when in its charge carrying position oc-` cupies the position shown in full lines in Fig. 2 and occupies the dotted position when in its dumping position at the right hand extremity of the runway. The runway is shown mounted upon a suitable frame work l2 which can in any manner be mounted upon the vehicle or form a part of the vehicle as shown. The hopper has rails 13 to coperate with the runways 11. My im- Specification of Letters Patent.

proved holding means consists of a pair of brackets 11i. and l5 these brackets consist ing of two strips 16 and 17 preferably of angle iron, which are pivoted upon a stud or shaft 1.55.` The shaft 18 is carried in the frame work l2. The upper extremities of the strips 16 and lW are united by two straight strips of angle iron to form cross pieces, respectively the strips 19 and 20. The hopper ends are each provided with coperating angle iron strips 2l which interlock as more clearly shown in Fig. 2l. .fi small. section of T-iron E22 is riveted to the angle iron section and is provided with a slot Qlinto which the protruding tongue of the strip 2O may project. Then the brackets are in the position shown in Figs. l, 3 and it will thus be seen that they interlock with the locking elements 2l and 22 provided upon the hopper ends. In order to release the hopper the lni'ackets" ldiand l5 are swungoutwardly as shown in .lotted lines in Fig. l. In order to swing these brackets simultaneously I provide suitable means which may, for instance, consist of the tension elements 24. and 25. These are linked at their extremities to the brackets le and l respectively. As the pivotal point of the brackets lies between the mounting point of the elements 9A and 2.5 it will readily be seenthat as one bracket is swung outwardly` the `other bracket must follow suit. A strong sprintf Q6 normally holds'the brackets in their locking position. From the above description the nature of my device will be readily apparent to those skilled in the art and its simplicity will be peculiarly apparent. I have herein dcscribed but one form which my invention may take but claim as my invention all such forms as are within the scope of the appended claims.

I claim:

l. In a device of the character described, the combination with a runway, of a rolling hopper movable thereon, and means for holding said hopper in its central position upon said runway, said means including a of vertical interconnected tiltable brackets pivoted near their lower ends and mounted at opposite extremities of said hopper, movable in opposite directions toward and away from said hopper.

2. In a device of the character described, the combination with a runway, of a rolling hopper movable thereon, and means for holding said-hopper in its central position upon said runway, said means including a pair of vertical tiltable brackets pivoted near their lower ends and mounted at opposite extremities of said hopper movable toward and away from said hopper, and means for causing the simultaneous movement of said brackets. n

3. In a device of the character described, the lcombination with a runway, of a rolling hopper movable thereon, and means for holding said hopper in lits central position upon said runway, said means includingl a pair oi tiltable brackets mounted at opposite extremities oi said hopper movable toward and away from said hopper, and a link uniting said brackets to cause the movement of said brackets simultaneously in opposite directions.

4. In a device of the character described, the combination with a runway, of a rolling hopper movable thereon, and means for holding said hopper in its central position upon said runway, said means including a pair of tiltable brackets mounted at opposite extremities of said hopper movable toward and away from said hopper, said brackets having cross pieces and the ends of said hopper having coperating cross pieces to interlock with the cross pieces upon said brackets. f

5. In a device of the character' described, the combination with a runway, of a rolling hopper movable thereon, and means for holding said hopper in its central position upon said runway, saidV means including a pair of tiltable brackets mounted at opposite extremities of said hopper movable toward and away from said hopper, and means for causing the simultaneous movement of said brackets, said brackets having cross pieces and the endsof said hopper having coperating cross pieces to interlock with the cross pieces upon said brackets.

6. In a device of the character described the combination with a runway, of a rolling hopper movable thereon, and means for holding said hopper in its central position upon said runway, said means including a pair ot' tiltable brackets mounted at opposite extremities of said hopper movable toward and away from said hopper, and a link uniting said brackets to cause the movement of said brackets simultaneously in opposite directions, said brackets having cross pieces and the ends ot' said hopper having coperatmg cross pieces to interlock with the cross pieces upon said brackets.

7. In a device of the character described, the combination with a runway of a rolling hopper movable thereon, a shelf projecting from each extremity of said hopper, a pair of tiltable brackets having a shelf adapted to coperate with the corresponding shelf' upon the hopper for holding said hopper in its central position, and tongue and groove means provided upon said hopper and brackets to further lock said hopper in its central position.

8. In a device of the character described, the combination with a runway, of a rolling hopper movable thereon, means for holding said hopper in its central position upon said runway, said means including a )air of interconnected tiltable vertical brackets pivotally mounted at opposite extremities of said hopper with their upper ends movable in opposite directions toward and away from said hopper, and means for holding said brackets in operative position.

In witness whereof I hereunto subscribe my name this 16th day of October, A. D. 1918.
